Abstract

Poudre photocatalysante pour la purification de l'environnement, qui comprend des particules fines d'anhydride titanique et une couche d'enrobage poreuses de phosphate de calcium formée sur au moins une partie de la surface des particules, un surfactant anionique étant présent au moins au niveau de l'interface située entre la surface des particules fines d'anhydride titanique et la couche d'enrobage de phosphate de calcium. On produit la poudre photocatalysante en dispersant les particules fines d'anhydride de titane dans une suspension aqueuse contenant un surfactant anionique et en formant ensuite une couche d'enrobage poreuse de phosphate de calcium sur la surface des particules fines. On utilise ladite poudre photocatalysante, par exemple, sur un support polymère organique moulé.
